Ammonium Nitrate Fuel Oil (ANFO) — Decomposition

Ammonium nitrate fuel oil (ANFO) is a mixture of solid ammonium nitrate and mineral oil. Easy handling allows it to be used safely in mining, stone quarrying, and tunnel construction. The basic reaction during detonation is the decomposition of the hydrocarbon and the ammonium nitrate into CO2, nitrogen and water. For this test a mixture of NH4NO3 and toluene was used. Three phase transitions (endothermal peaks) up to 150°C and the large exothermal decomposition peak starting at approx. 235°C can be detected. (measurement with MMC 274 Nexus®)
